Hey, I have a '94 LT1 w/ 6-speed manual. And i just recently ordered an exhaust system for my car from headers to mufflers. The headers are being made, so they have not been sent out yet. For potential resale reasons, i wanted to keep as much emmisions stuff as possible. That goes without saying that there is no cat with this system, it is straight pipe, but should there be need for a cat, then there is a removable section i can utilize to place one.
Getting to my point, as i was ordering the system i learned that there are several questions that i wanted to ask, they said that they do not provide an LT1 EGR tube, well so i asked for block off plates, but they do offer the headers with the air pump holes, so i told them to put that on. Well upon inspecting my engine during my routine winter maintenence, i wanted to see where the EGR tube was, apparently it is connected with the air pump hoses, i could not trace an individual pipe from the EGR inlet, next to the EGR valve, going directly from header to intake (like my last car, a LT1 Camaro). So, is my hypothesis correct, i will not require any special block off tubes as i thought and that the EGR system is interconnected with the air pump system?
In addition, i knoticed that my car has a after cat O2 sensor on the passenger side, are there any O2 simulators out there to rectify any issues since i am not utilizing it? The last thing i want is my computer reading that something is missing and risk the potential of it "detuning" the engine? Or will i simply need to tune out the aftercat O2 sensor?
Note that where i live, there are no emissions laws, so tests are not of any concern.
Thank You,
Will
